The Best Water Filters

best water filters

I’ve been reviewing water filters for about 16 years. These best filters I’ve found for most people are:

  • For well water or other problematic water, I recommend Big Berkey drip filters. These filters use a combination of ceramic and carbon block filtration. Overall, they are the least expensive type of filters to maintain.
  • If you are only interest in a pitcher filter — this BWT filter will remove most contaminants
  • If you are able to spend $1500 to $3000, “whole house” filters are the an inexpensive long terms option. These filters are installed at the pipe where the municipal water pipes enters your home. I recommend the whole house filter by Pure Effect.

The Contaminants You Want To Remove

Typically, you want to remove these contaminants from your water:

  • Toxic metals (Lead, Mercury, Aluminium, Cadmium, Chromium, Copper, etc.)
  • Additives (Chlorine, Chloramines, Fluoride)
  • Chlorination By-Products (Trihalomethanes or THMs)
  • VOCs and other Organic Compounds (Pesticides, Herbicides, Pharmaceuticals, Fuels)
  • Bacteria and viruses (Giardia, Cryptosporidium, etc.)
  • Radioactive substances (Radon and Uranium, etc.)

If you use municipal water, you will usually find these contaminants:

  • Chlorine
  • Chloramines
  • Fluoride
  • THMs (Trihalomethanes)
  • VOCs (volatile organic compounds)

If you use well water, these are the most common contaminants you’ll find:

  • Particulate matter (dirt, bits of leaves, etc.)
  • Bacteria and viruses
  • VOCs (volatile organic compounds)
  • Radioactive substances

The Effectiveness Of Different Types Of Water Filters

Pitcher Filters

Pitcher-style filters such as Brita filters are inexpensive units, making them very popular with consumers. However, in the long term, they are actually one of the most expensive option. The filters cartridges require frequent replacement — the cost for 40 gallons is $7-10 each, or $130-$190 for 750 gallons.

Almost all pitcher-style filters use GAC or “granulated activated carbon” as the filtration medium. Typically, GAC is coconut husks that have been heated to a high temperature in the absence of oxygen and then granulated. These filters do remove some chlorine and hydrogen sulfide (rotten eggs odor) — but are not effective at removing VOCs, metals, pesticides or fluoride. Overall, they are not very effective water filters.

Faucet Filters

Filters that attach to your kitchen faucet are very similar to Pitcher Filters, but they do filter a little better than the pitcher-style filters. However, they have the same drawbacks — they are expensive to maintain and they do not remove many contaminants. You must replace filters every 100 gallons at $20-$40 each or $140-$180 for 700 gallons.

Colin Ingram, author of the The Drinking Water Book rates all faucet filters no higher than “Acceptable”.

Gravity-Fed Drip Filters


In my opinion, the best water filters are gravity-fed drip water filters. These filters are excellent at removing chlorine, chlorination by-products, fluoride, VOCs, pesticides, particulates and pharmaceuticals. These filters use “candle” type filters, which are widely available and can be customized to your specific filtration needs.

Gravity-fed filters require no electricity to operate — water is filtered as it drips from the upper chamber to the lower chamber. Because the water is filtered slowly, the filtration is much more effective than a faucet-mounted filter. Generally, slow filtration methods tend to be best.

Berkey is best-known drip filter manufacturer. They make good quality filters. You might also consider ProPur filters. Their latest filter, the ProOne G 2.0, will remove fluoride — including hydrofluorosilicic acid (few filters remove this contaminant).

These filters use carbon block filtration, which works by the process of adsorption (different than absorption). In this process, the carbon attracts certain contaminants at the molecular level, and the contaminants become attached to the surface of the carbon. Once the surface of the carbon is full, the filter must be thrown out and replaced. However, the ProPur filters can be periodically scrubbed, and thus reused for years.

These filter are certified to NSF/ANSI standards #42 (test for chlorine, taste, odor and particulates), NSF Standard #53 (tests for Cryptosporidium, Giardia, lead, VOCs and MTBE) and NSF Standard #61 (tests that toxins aren’t leached into water). They are manufactured in England.

Berkey filter are available from Amazon for about $300.

Overall Rating: Excellent

Reverse Osmosis Filters


Reverse Osmosis filters use a membrane which removes many contaminants from water. They are usually paired with a Granulated Activated Charcoal filter to remove chlorine. Most reverse osmosis filters are installed under the sink and have a holding tank. The semipermeable membrane separates many contaminates (which usually have a larger particle size that water) from the water and rejects a large amount of water in the process. The result is a waste of several gallons of water for every gallon filtered and many naturally occurring minerals (including calcium and magnesium) are also removed from the water.

However, they are quite effective filters, in terms of removing contaminants. However, they do not reduce VOCs or pesticides (unless a Carbon Block filter is included). They can take up to an hour to filter one gallon of water and the filters need to be replaced regularly.

If you want to go this route, I recommend the iSpring Reverse Osmosis System, which is quite reliable.

Overall Rating: Very Good

Countertop Distillers

Countertop distillers are effective water purifiers, but they take some time to distill water (for example 5 hours to distill 1 gallon). They also require electricity to run, and they give off some heat and the integrated fans make some noise. Also, most distillers do not remove VOCs (like benzene) because they have a lower boiling point that water. So they will vaporize together with the stream, resulting in a contaminated distillate.

Countertop distiller that get a rating of “Excellent” from Colin Ingram in the The Drinking Water Book are: Megahome Countertop DistillerWaterwise 4000 and Waterwise 8800, Kenmore 34480 and Pure Water Mini-Classic.

Megahome Countertop Water Distiller


This distiller is sold under many brand names — it’s the most widely distributed distiller in the world. It has many quality components despite being inexpensive. It produces 1 gallon of water in 5 hours. The water is passed through a small granular carbon filter. There’s a sealed connections from the distiller to the water collection container, so there is minimal risk of contamination by air. The unit has a stainless steel boiling chamber that is easily accessible for cleaning.

The Megahome Countertop Distiller is available from Amazon for about $150.

Waterwise 4000 Countertop Distiller

best water filters

This is a more powerful version of the distiller listed above. It has the same features but produces 1 gallon of distilled water in 4 hours. Also received an “Excellent” rating from Colin Ingram in the The Drinking Water Book.

The Waterwise 4000 is available from Amazon for about $320.

  2. I often wonder about those vending machines that fill your 5 gallon bottles with filtered water that costs 39 cents a gallon commonly found in grocery stores . there is also water shops dedicated to fill your bottles, sell bottles, water coolers, etc and they are a bit cheaper like 30 cents a gallon. Are those the best or better than buying your own water filtration system under sink or on countertop? As long as I am still young and able to haul heavy 5 gallon bottles ( I use 3 gallon bottles) with water softener, am I buying the best drinking water money can buy ? what about water delivery service that costs considerably more, of course?

  3. Hi there,
    Thanks for the awesome article!
    I drink tons of water a day and really care about the quality of water I drink. Currently, I use a refrigerator with a dispenser and then consume refrigerator water filters on a regular basis, about 6 months.
    The refrigerator water filters I bought adopt the high-quality filtration system and use active carbon blocks to remove impurities. Most importantly, the price is inexpensive, I don’t want to buy fridge water filters from original manufactures which are very expensive. I would like to buy water filters from a third party with a much lower price and premium quality. If you ask me the name of the third-party seller.
    I tell you it’s
    This website offers a wide range of brands of water filters at very affordable prices. And the return policy
    is awesome! At the very beginning, I bought the wrong filter and would like to return the filter. Then I contacted customer service and they offered me the no-hassle return.
    I have been buying refrigerator water filters from for almost five years. And I recommend the website to many of my friends. They really love it.

  4. This is a really thorough review of the systems I’ve seen yet so thank you!
    I purchased a Big Berky last week from Amazon. I needed to watch a YouTube video to figure out how to set up, which took maybe 30 min to do. But after that, it’s perfect. The steel containers are sturdy and the filter really does clean the water better than any other system I have used.

  5. I do not get the buildup of lime around the kitchen sink or the shower walls any longer. The water tastes as good at every faucet in the house. Previously only the water from the refrigerator would be Aquasana good, because of the built in filter. Installation was without the pro installation kit. This being my preference. See photo attached.

  6. I have been using the Kangen for years, thinking that it was a water filter as well as ionizer, but was recently informed by a friend who markets Multi-pure (which I had used for decades) that Kangen water is not at all well filtered for contaminants. I am not sure what to do next as I was given the expensive Kangen water machine as a gift.

  7. RO system does a great job filtering water, but the investment is no joke; still, it’s worth it. The best out there are those that reintroduce minerals during the last stage of filtration (such as Home Master TMHP Reverse Osmosis). After all, the right water filter depends on what contaminants are there in your water, and how much money are you willing to spend.

  8. I’ve had the waterwise, thought it was a bit metal tasting, reverse osmosis counter top, which I loved , but after many many years the cords blew out, so now I am with gravity system , I went with AlexaPure vs Berkey , seemed similar . I got filter today and ran it thru a few times , I’m disappointed in the high tds number . How do I know it’s doing anything? Do you have any opinion on this product vs Berkey? I have a return window.
    Thanks for all the insight.

  9. This is an excellent article that provides the three best methods for complete water filtration. RO and distillation give you the lowest TDS and ensure that you remove the most contaminants, while Berkey is the best alternative that’s even powerful enough to treat untreated water in the wild. The coolest thing about Berkey is it’s gravity-fed, so it’s great for survival scenarios and outdoor uses such as camping. Thank you for sharing!

  10. I have been using the Kangen for years, thinking that it was a water filter as well as ionizer, but was recently informed by a friend who markets Multi-pure (which I had used for decades) that Kangen water is not at all well filtered for contaminants.

  13. In addition, soft water plays a big role in countertop water filters. I think hard water can damage when used in filters which I think having a water softener is good for your countertop water filters or even water filter systems. Though, there important details to remember when you get water softener such as the regeneration process which you can read in Anyways, soft water is not only good for your filtration systems but also to your home appliances, pipes, faucets, showerheads, and even your skin and hair health.

    1. Your comment is misguided.

      Well water requires different filtration — it mush be filtered for sediment, radioactive contaminants and pathogens.

      Municipal water requires different filtration (as outlined in the article).

  16. If you need a water purifier, i can recommend, i have been using their water purifier in my house for many years. their systems have a 2 filtration with a activated carbon filter and also a built-in uv sterilizer.

    me and my whole household find the water tastes so much better and we cannot drink tap anymore from the awful chlorine smell!

  17. Great article.
    I write to you from Spain.
    And I’ve come here looking for information about how effective or not water purification jugs are because I plan to buy one for a long trip to the countryside and I don’t want to put my children at risk with contaminated water.
    Here, I leave an example of the models I’ve seen so far:
    I wish you could help me with this doubt.
    Thank you.

  20. Thanks for spreading the awareness about the fillters ,your article is very informative … it covers almost all information about how the reverse osmosis works and how much it important for the pure water.

  21. Hello
    I live in the UK and I have been advised that the Aquasana powered counter water filter was very good. So i recently bought one but am having a few issues with the new filter not working , at least the red lights to show it’s out of use, continue and so far the customer service in the UK has proved to be very poor.
    Do you know about these filters please?
    Kind regards

  22. So I own a Berkey water filter. What I find disturbing is that the filters themselves fail. You are supposed to test your filters prior to using the Berkey and at 6 month intervals. Mine have failed twice in two years both at the 1 year point. My question to you is there a generic charcoal filter out there that might be made better? I want to keep using my Berkey but I am not happy with having to check them only to find out they have failed again.

    1. Hi Tina
      You don’t need to check them every 6 months.
      No need to check them at all actually.
      Just prime and clean then every 12 months.
      We own Berkey and all out family for the last 6 years already.
      We spent £250 or something like that 5 years ago at official Berkey Waterfilters Shop in Europe. and we haven’t spent anything extra since then.
      Amazingly cost effective and we haven’t bought a single plastic bottle since 2013 🙂
      I love there systems.

    2. Tina, go to this website to check Berkey authorize dealers.
      There are lots of counterfeits and fake products in this age, and this applies to Berkey filters as well. So try to find a seller that has been sanctioned by Berkey. See for some explanation about this.

      Also, some unauthorized dealers are listed here, but not all (not all is known)

      Perhaps that might help, esp if the filter in your Berkey is not authorized.

  23. Hi, I must agree with you that pitcher filters and faucet are quite bad. Although there are exceptions amongst them, I have found ZeroWater and Aquagear to be decent.

    Apart from that, I think Big Berkey is a good choice when traveling, or as the RV option, but for the home, I think there are better options out there for larger volume especially if you have family.

  24. One of the advantages of using these Gravity-fed filters is that it does not require any electricity to operate. I would highly recommend you to purchase it guys Thanks for sharing this wonderful info.

  25. I have been using the Kangen for years, thinking that it was a water filter as well as ionizer, but was recently informed by a friend who markets Multi-pure (which I had used for decades) that Kangen water is not at all well filtered for contaminants. I am not sure what to do next as I was given the expensive Kangen water machine as a gift.

    1. This whole article is very misleading. My advice to anyone with water concerns is to get their water tested from a state certified lab, then get several estimates from water treatment professionals based on your particular water test. Don’t take advice from an article on the internet.

        1. Thank you for providing such a detailed evaluation of the systems I’ve seen thus far!
          Last week, I ordered a Big Berky from Amazon. I had to watch a YouTube video to find out how to set everything up, which took about 30 minutes. But it’s great after that. The steel containers are strong, and the filter cleans the water better than any other system I’ve tried.

  26. I’ve been doing some research on the filtering well water and actually hadn’t seen the Berkley drip water filter you’d mentioned. It’s a very cost effective way to make the water safe and drinkable. I was looking more down the whole house filtration system and as you have said.. the costs probably make sense over the long run, but in the short term they do stack up!

    1. Hi James, you’re surely be very professional to pick up the best refrigerator water filter supplier in the replacement market.

      I’ve got a good one to share with you, i think that you will be surprised by its premium quality and fantastic performance.

      Recently i’ve received a free giveaway from , a one-stop ODM&OEM water treament solution for global customers, a genuine brand certified with NSF 53&42 water filters manufacturer located in the US.

  28. Wow, wow, WOW!

    PUR makes some pretty bold claims at

    MAXION® Filter Technology. Certified to reduce over 70 contaminants including 99% of Lead, 96% of Mercury, 92% of certain pesticides. More than any other brand.*
    *As of 10/3/2018, NSF certification comparison valid for faucet mount and pour-through filters.

    For Berkey, it’s claimed: These filter are certified to NSF/ANSI standards #42 (test for chlorine, taste, odor and particulates), NSF Standard #53 (tests for Cryptosporidium, Giardia, lead, VOCs and MTBE) and NSF Standard #61 (tests that toxins aren’t leached into water). (This is different from a claim that they are certified *BY* the NSF; where, if anywhere, does Berkey make the latter claim?)

    PUR systems are certified *BY* the NSF – search for the filter – their RF-9999, listed under a parent company: Kaz USA, Inc. a Helen of Troy Company at . The NSF states:
    “If you would like to confirm a filter or treatment system is NSF certified for reducing lead in drinking water, please call NSF International’s consumer information specialist at 1.800.673.8010 or send an email to”
    Furthermore, Kaz/Pur/Helen of Troy’s filters, per are certified to NSF/ANSI 42, NSF/ANSI 53 AND NSF/ANSI 401 (They’re for Aesthetic Effects, Health Effects, and Emerging Compounds/Incidental Contaminants – the exact filtering is detailed on that page.) . This is ALSO documented at and on the label (photo: )

    It looks to me like gravity-fed filters are much less effective than faucet filters*. Tap water pressure (which is many times greater than in gravity-fed) provides energy that allows them to have much finer filter particles but still filter faster than the gravity-fed ones. *See for specifics. Maybe Berkey is an exception, but “401” (NSF/ANSI 401- for Emerging Compounds/Incidental Contaminants) is not mentioned in ANY of the reviews or comments on this page – ’till now.

  29. I have a megahome water distiller to make distilled water to drink. It is very easy to use and requires no installation. I don’ want invest in an undersink water filter (a ro system), because such a distiller offers me enough potable to drink. Maybe in the future, when I have a counter with enough under counter space, I will choose to install such a RO system.

    1. hi Danny

      I just came to this forum since i am doing reaserch on comon problems with tap water. I am working on one project with two inventors from EU (Slovenia). They developed totaly new aproach on water tretment. The discovery was by acctident and results are incredible.
      For four years they were developing and patented Kinetic technology closely in cooperation with national laboratories, private laborratiories, chemical institutes, chemistry faculty, Munich University, Slovenian goverment and EU cohesion policy that give recognition of the strategic importance of technology.
      The thing is that Kinetic reactor on tap and designed chamber inside brings water to hydrodynamic cavitation. Additional when water cavitate it produce vacuum and shear force of jets after which the cavitation is also known. A series of these phenomena trigger oxidation and degassing of water pollutants

      Countless analyzes have been made. And results was that:
      – increase the efficiency of chlorine and thus eliminating it by 40% or more.
      – The result is a reduction of the bacterial content (coliforms, e-coli, clostridis, legionela …)
      – Since degassing of carbon dioxide occurs lime stone is molecular transformed into aragonite structure (dust)
      – General reduction of metals and heavy metals up to 10x
      – Partners from Hungary-Sopron were doing tests on pesticide Arsenic and they were immediately confident in the technology since they reduced from 25 mg / l to 3.75 mg / l just with small foucet Kinetic Reactor.
      – Decrease opacity
      – Now we are doing tests on microplastic, Endocrine disruptors…
      – Allium tests are beeing done because we noticed that the water becomes much more susceptible to the body and less water is needed to dring for a sense of be hydrated.
      – Overall the improvement of the taste of water is instant.
      – And product itself provides much more safety in drinking water from the tap

      There are also blod analyses and positive effects but i would not like to get into that because there are not enough analyzes done.

      It was very interesting when i heard that the well-known Indian guru is talking about cleaning properties of cavitation. But until now there was no real technology.
      If you want to learn more contact me on i can send you some detail of what we do.

    2. Hey Danny,
      You do not need to invest in an undersink ro system, there are currently 2 great options online i just googled.
      1- Aquatru see “ ”
      2- Puricom Countertop see “”

      I am personally biased since i have a Puricom countertop (previously known as “ZIP Puricom” ) in my office.It is awesome! 4 stage filter, NSF/ANSI 58 Certified 75 Gallon Per Day Reverse Osmosis Membrane, taste great! Zero installation, just plug it in.

      Here is a review i found:

      Only one regret with the Puricom Zip, I bought it last year and this year they are cheaper and doing promotions.

  30. If you’re going to go with reverse osmosis, I think it’s important that your water filter also come with a remineralizer, since all the essential (ie calcium/magnesium) minerals are also stripped. Or as you mentioned, go with something like the big berkey with a fluoride filter.

  32. We have RO on our Refrigerate well water. I like to fill a pitcher of water up for the coffee pot in the morning. Is a Pur water filter pitcher safe if you already have RO well water? Or should I take the filter out of the Pur water filter and just use it as a pitcher. Thank you

    1. If you already put the water through reverse osmosis, you probably won’t gain much more filtration from a pitcher. So I’d say you could remove the filter.

    2. Last month i’ve bought 3PKs Pur Water Filters for our Whirlpool 4396710 Refrigerator , and it can be a good filter cartridge replacement for my parents’ Kenmore 9030 fridge as well.

      I’d like to share my fantastic shopping experience with you at, it’s a newly-started water filters store, and all kinds of refrigerator water filters at retail prices to be chosen.

      What’s the most surprising thing for me is the factory outlet price i get to buy them spent less 20% off the regular price of convenient store in the market.

      And it only took 9days for me to receive my filters, but it’s ok for me, i like it and moved by its careful packing and unbeatable cost-effective.

    3. Hey Vivian, your comment ” I like to fill a pitcher of water up for the coffee pot in the morning” rang a bell in my head.
      You have got to try this:
      They sell arguably the best ro countertop system and throw in mineral packs for brewing coffee.
      Since you already have an ro well water installed you could just get the mineral packs.
      The main guy is from Minnesota and is a water quality association expert, and also a Specialty Coffee Association expert.
      I tried the mineral packs and wow my coffee never tasted better.

    Been using it for 10 years almost and all my family members in UK are also using it.
    Highly recommend this filters.

  37. I spent the last few hours reading all of these comments. It is amazing to me how everyone says their system is the best. I bet non of you have actually had the water from your so great system analyzed for anything except maybe a basic generic test for lead etc. it also sounds to me like Berkey somehow is all over this comment section ???? I looked at the Berkey site and they have absolutely no concrete info on how their system really works or any definite claims on what it removes. It is all smoke and mirrors. I would be interested to see who is actually behind this site. Propbably berkey

    1. Hi Odette ,
      I’m extremely sensitive to heavy metals and petrochemicals. I came across the Berkey filter gravity system 15 years ago… it is amazing! I had the tap water which was contaminated with lead, put through the filter , then tested at a clinic…the berkey had filtered the lead completely. The Berkey has been used in remote locations in Africa where there’s a lot of water borne disease and it’s amazing at cleaning the water. I’m not surprised the Berkey is on top of the best selling list!

    1. I am also interested in knowing about the Nikken filter. Friends have recommended both Berkey and Nikken. Was just getting ready to research Nikken (which led me to this site). Thank you in advance.

  38. It seems to be that we should equip one in our house to stay healthy. Thanks for the suggestion. I will check these out to see which brand is good to go with while I have limited budget for this.

  40. I am still a fan for reverse osmosis filter. They are just excellent.
    Distillation is the best filtration system. But it is just taking too long to produce clean water for consumption. 4-5 hours per gallon can’t serve a household of 4 people.
    I think it will add in more cost by using electricity. Correct me if I am wrong.

  41. I would like to add another water filter which is also the best in industries.
    Woder water filter is also the best filter system. You can easily remove 95% of the fluoride from your water supply by installing the Woder® FRM Fluoride Filter. In addition, it eliminates lead (99.9%), heavy metals, chlorine (99.9%), chromium 6, mercury, volatile organic compounds, carcinogens, and other contaminants, as well as turbidity, odors and tastes.

  42. I use reverse osmosis water and run it through a water distiller.
    The reverse osmosis water shows 12 to 17 impurities.
    The distilled reverse osmosis water shows zero impurities.
    If being worried about minerals, add sea salt.

    1. Hi Bob,

      Our testing confirmed most commercial brands of sea salt itself contains high levels of heavy metals and VOC contaminants (depending on where it is sourced). Problem too often with those from the ‘naturalist’ community, is the absence of science and facts to base opinion. Sea Salt (while often far more dangerous than table salt varieties) has become the baking soda/vinegar cure all seasoning of the Naturalist community. Food for thought.

      1. Hi Chris – regarding heavy metals in sea salt – can you give any citations for this claim?
        Is eating sea salt more of a risk than eating say tuna would you say?

      2. No need to disparage the “naturalist” community and sea salt . Unfortunately, everything that comes from the ocean today is contaminated by microplastics to some extent. Shellfish are the most contaminated — far more than sea salt. See this article for example:

        Besides shellfish and fish, they say these items tend to be contaminated with microplastics:

        Beer, honey, salt, drinking water, and mineral water.

  44. I am reading all these wonderful reviews of Berkey and trying to understand why our experience has been so different. We have gone through at least a dozen filters over the past year. They have all failed the red food dye test either right away or within a couple of months of use. When they did fail, it was usually mid cycle (meaning we filled the canister full, and monitored it until filtered all the way through – about midway it began leaking pink water). We used them to filter regular tap water. We have sent photos and video recordings of our tests to our distributor and they did not see anything we were doing wrong. Then we sent our filters for them to test and somehow their tests came back completely normal…. I don’t know how to explain this, and don’t know where to go from here. I don’t feel comfortable drinking water from a filter that (at my house) lets red food coloring through – to me that means that everything else is also leaking through. In addition to that, the water doesn’t taste very good (even with weekly washing the bottom canister with vinegar and dishsoap). Even our kids much prefer to drink spring water from a gallon rather than our Berkey water.

    Now I feel like I really can’t trust any water filter manufacturer out there…
    If anyone has any ideas of what might be going on, I would be extremely thankful!

    1. Hi Anna,
      We bought the Berkey because of all we read about it. We had the same experience as you. We truly want to love the water and can’t stand the way it tasted. Tap water tastes better. We primed it successfully and poured out many gallons only to find the taste of the water had been altered every time. We felt it wasn’t drinkable. We didn’t do the dye test on it, which we will do when we set it up again. We decided to store the unit in case of emergency. Honestly though, i would rather drink any other water than what was being produced by this filter. We had heard about the Berkey filter recall which apparently had filters that were falling apart after use. Very disappointed.

    2. Dear Anna
      I do not have a berkey filter but I notice that by comments that seals may be an issue .Second make sure the bottom is well cleaned with hot water to rid of soap and vinegar.The filter cannot take hot water,cleaning the top may cause problems with the seals .For a portable filter one is advised to use lubricating oil to fit seals or O rings,which may help in your case.In another post it was noted that the seals leaked…
      hope this helps

    1. Second the comments about testing aquatrue, that, and the part in the article about 1 hour for 1 gallon is simply not true.
      Another great countertop that has great reviews, zip puricom.

  46. I do not agree with this statement. ” However, they are quite effective filters, in terms of removing contaminants. However, they do not reduce VOCs or pesticides (unless a Carbon Block filter is included).”

    A typical ro membrane has a chlorine tolerance of 0.1 ppm. This means if you’re on a city water supply, you would need to remove chlorine as a pre-treatment before sending water through the ro membrane. Majority of US consumers are on city water. Thus, almost all ro systems, even the iSpring system that’s linked by the Author has THREE types of carbon filters in the system.

    iSpring, WECO, APEX, Watts are all good ro systems. When considering water waste, however, WECO wins with their new VGRO series ro systems.

  47. First, “removing contaminates” is new to me. As far as I understand there’s no machine in the world that can do that. Reduce, I understand.
    2nd, reverse osmosis system is not the best unless you like to drink dead water, free from minerals our bodies need.
    3rd, what contaminents? Every area has its own supply of contaminants and different qualifications of what is “safe”. Beside in comparison to the hundreds of contaminates we have in some areas, how many are really being tested?
    Also there are different groups such as, bacterias, viruses, esthetics…..
    I would love for you to check out the water filter I use, MultiPure. See the NSF Certifications of the different contaminates.
    I LOVE IT! AND I’m drinking clean, pure and live water.

  48. @Mike. Let me CORRECT you here. These statement from you are simply not true!
    I’m a water plant / wastewater specialist myself. Based in UK with all my background & studies in USA.
    First of all. California and Iowa have completely different standards and laws for sellers of water filters.
    Thats why almost no USA sellers are shipping water filters to Iowa and California.
    California laws states you need to use only handful of ”selected” lab companies in California to test and then sell any water filtres.
    This is why almost no one dares to sell their water filters in California as they need to pay high amount for only these 2 states..
    Most sellers don’t ship to these 2 states because of this.
    Berkey is by far the best water filters on the market and in the world today as this article states as well.
    I have been using these systems in work and home for almost 7 years now and i tried almost all alternatives on the market before going over to Berkey.
    RO (reverse osmosis) are fine too but Berkey are much more powerful and they don’t remove the magnesium and calcium from the water.
    In UK we have high amount of magnesium and calcium in the water so these minerals are essential for our bodies.
    Most cheaper filters like Brita and other brands remove this good minerals so i would never go for these brands.

    Berkey is one of few filters on the market that are classed as a Water Purification Elements.

    To get these certifications you need to have much higher standards then normal water filters.

    Do your own research and you can see this is the reason Berkey is not Sold or tested in California. (they can be tested there of course. But…. (each water sample takes minimum 6000 USD for full lab tests if i remember correctly)

    Berkey have been tested hundred of times in the USA and EU over the years and they always comes out as the best on the market.
    Please do your own research and stop spreading some false claims like these.

    All the best

    1. Being that you’re a water expert, would you please clear up the value of knowing or not knowing the Total Disolved Solids reading of water.
      Here in Nevada, the water out of the tap reads 395 on the TDS meter…
      The water that comes out of our sons Berkey system reads 385 on the same meter, not much of an improvement.
      The water out of our distiller reads 4 TDS and the ZeroWater reads 0…

      So what’s the verdict on TDS readings?

  50. Hello,

    First of all thank you for writing this article, it was very informative. I was wondering if you know how the Radiant Life Series 6 whole house filter ( ) compares to the whole house filter by Pure Effects ( We are looking to purchase a whole house system, water conditioner and undercounter filter. Just wondering pros/cons/recommendations regarding a whole house system (Radiant Life vs Pure Effects) and if you can help us make a decision.

    Thanks !


      1. Hi Sarah/DeeDee,

        I have not heard a response back yet and I am still deciding. Leaning toward the Radiant Life series myself as regular maintenance seems to be cheaper than with the Pure Effects system which requires many filter changes. We are in need of a water softener/conditioner as we have hard water as well as a purification system. I am also interested in the Berkey. Not sure if we will go with a mix of the Radiant Life for whole house and Berkey for drinking (point of use). Just wish good health did not come at such a high cost 😉

        Also if anyone else wants to weigh in on these systems (Radiant Life, Pure effects, Berkey) and a comparison that would be greatly appreciated.


  51. Great post guys and this helped me a lot! I have been doing my own research here in the UK and we have now bought a Big Berkey here in the UK and I we LOVE it! Never tasted such a clean and nice water with my water purifier. There is a lot of filter options out there but what I been reading the Berkey really are the best and they last so long too!

  52. Vernika Sharma

    Recently I bought Kent water purifier as it works on reverse osmosis technology which helps in killing bacteria, germs, and virus.I am very content that it provides 100% pure water.At last, I would say, Never take a chance with your health.

  57. I just bought a faucet filter, so we can use a filtered water in cooking. While for our drinking water, we have a water delivery company and the delivery schedule is thrice a week. Do you think, I still need a water treatment at home? Please do advise so I can ask for an assistance about it. Thank you in advance.

  58. Berkey filters are. oT certified by NSF. This can be verified by checking the NSF website. Additionally Berkey now can’t claim it “purified water” in the state of CA. Lastly, ask Berkey for their technical test report. They’ll send you one saying it was done to NSF standards, by Louisiana University. Simply email and ask the university. I did. And their email states they never tested any Berkey filters and that it is a fraudulent technical report. All of this can be checked by checking with the Stste of CA, the NSF website, and the testing laboratory provided by Berkey. Berkey “filters” water. It does not purify.
    All I’m saying is verify before you buy ANY water system. NSF keeps a listing of all water purifiers they have tested.

    1. Hey Mike! I was wondering if you would be willing to share your findings on Berkeys test results. What I have found out; I was in contact with Berkey customer service, who told me that their testing is done by a third party, Envirotek Laboratories Inc. I have reached out to Envirotek Laboratories, and have also been in touch with the EPA about Envirotek accreditation, and I haven’t found that the results they supply on Berkeys website to be false. Not once through my contacts was Louisiana University mentioned. I don’t like to be lied to by a Company, especially when it’s in regards to a rather expensive item that I am purchasing for the health of my family. I have not yet opened my box, but if they are in fact providing false results just to gain customers, I don’t want to be one of their test rats to see if I’ll notice. Thank you so much for your time!

    2. Hey Mike, how do I do my own research on the NSF website I live in NY and I want to purchase the Berkey filter but I want make sure I’m investing in the right thing.

  59. In the past water was not an issue, Today with an increasing demography, plolution also grows….but does it affect really the humans?
    In my opignion, except for the toilets, the water must be the same at all taps, more especially the kitchen.
    Therfore the bedt option is the triple filter system, to offer a certain level of uncontaminated water.
    If uou travel or go in hollidays, beet is to take with you a gravity filter.
    Do not be too much concerned on heavy metals, most of them will be stopped by filtration, the residues you may take will be eliminated by your body with natural chelation and antioxidents, with the help of the vegetables and you eat (parsley, avocados, tomatos, nuts, corriander, squash etc…)

  60. A good overview of filter systems available. l would just add two points. Regarding the slowness of RO systems, it should be pointed out that there are some reverse osmosis filters available which are ‘direct flow’ system. These are tankless and have a higher flow rate than many. Ecosoft & BMB both produce models of this type, though it should also be mentioned that they are more expensive.
    Also it is worth looking at filters utilising ‘active ceramics’ as media. These take out a very wide range of contaminants including fluoride & pathogens and has the added advantage of adding beneficial minerals back in to the water.

  61. Hi! I am constantly travelling, mostly in Europe, so I am looking for a system to take with me that does not take up too much space. What would you recommend? I am often about two months in each city.


  62. This review speaks very highly about Aquagear pitcher filter. It got me interested in this product. But then I noticed that the claims of the filter’s wonderful performance on the manufacturer’s site are substantiated by nothing more than testing statements from anonymous labs! There is a discussion of the same issue going on Amazon at the moment. The Aquagear customer rep has responded to the question in the most disturbing way: “Per our agreement with these labs, we are not able to disclose this information, but we can assure you that the labs that test our product a) have no affiliation with Aquagear b) use strict SM and/or EPA protocols and c) are accredited, usually ISO 17025 accredited.” The answer sounds totally fishy! There are 3 testing lab statements posted on their website, so “usually ISO accredited” does not make any sense, just as the testing labs asking to remain anonymous.
    So, I have two questions:
    By any chance, have you, the Mater, tested the Aquagear filter yourself?
    Do you know whether in the US there is any mechanism through a consumer inquiry to force the company disclose their testing labs?
    I would appreciate your help, as I need a pitcher filter and this ones claims to to do everything I need. I live in a historic home in Michigan, with lead service lines being almost a given. Can you recommend any other pitcher filter that will remove lead?

  65. According to my experience, pitcher filter don’t do much for your water quality (they remove roughly 10% of the contaminants). If you really want to improve your water quality, I suggest looking for an RO system. I personally have very good experiences with the AquaTru waterfilter, which are available in the US and EU. This filter has been thoroughly tested by the NSF, removing up to 99% of all the contaminants in your tapwater, and has been recommended by several experts (among them Dr. Mark Hyman).
    I’ve had the filter since august 2017, and so far, I’ve got nothing to complain.. The water tastes great, makes me feel good and it’s very easy to use.

    For more information:

    1. I’m glad you are enjoying your reverse osmosis filter, but there are plenty of water pitchers that have been certified by reputable laboratories for the reduction of contaminants.

    We have bought Big Berkey in our home already and everyone is happy here.
    We just used it for 2 months already and so far so good.
    I did alot of research also and they seem to be the best rated ones on the market.
    I see some people complaining about the price.
    I can not say it’s expensive compared to the lifetime of the filters.

      1. Hello,

        First of all thank you for writing this article, it was very informative. I was wondering if you know how the Radiant Life Series 6 whole house filter ( ) compares to the whole house filter by Pure Effects ( We are looking to purchase a whole house system, water conditioner and undercounter filter.

        Thanks !

  71. Big Berkey are the best.
    Just make sure you buy the original Berkey. Many replica out there and companies making similar products and sell as Berkey. We bought a ”Berkey” that we found out was British Berkfield after all. Not the original thing. So we ended up selling our ”Berkey” and then bought the original Berkey finally. Amazing systems. Just make sure you buy from official sellers and original Berkey. I do not recommend finding this products on marketplaces like Ebay.
    Amazon has original products i think. But i would not trust ebay as we bought our there and it was not Berkey…
    Official seller in USA are
    Official seller in UK and EU is
    Official seller in Canada is
    Then there are some selleer also in in Asia.

  72. hi thanks for writing informative piece of article. If it takes five hours for filtering one gallon, it works fine then. I am planning to install a filter on the bathroom faucet as well, do you think it can work for those bathroom sinks as well. How much Do i need to spend for installation cost?

  73. Hello,

    So glad I found this resource. Wondering if you have heard of the mitte filter. It just launched on Kickstarter. I’d be curious as to how you see it stacking up to the other filters reviewed and if it’s really as good as they say.


  74. One of the more inexpensive and at the same time convenient ways to get clean drinking water at home is with a water filter pitcher. It’s a must have item if you don’t have another water filtration system installed, such as faucet mounted, countertop or under sink water filter. Water filter pitchers might not filter as well as them, but it’s a step up from no filtration at all and they are inexpensive and convenient, as they require no installation.

    1. I bought Big Berkey about 18 months ago ( to filter rain water from barrel ) and all seemed fine. Then about a month ago my wife noticed the water was looking off a bit. I thought nothing of it but then she became quite ill with vomiting, stomach pain, head-ache etc. I got off lucky and got some stomach pain. So, I took a water sample to the Provincial test lab here in PEI and it came back as having high levels of coli form. So I checked all fittings etc to make sure nothing was getting through by the washers etc., cleaned the lower catch basin, faucet etc in bleach. Then I took an other sample and it failed again. I took multiple samples and all came back as do not drink due to high coli form levels. I might also mention that when traveling make sure you “carry on” the filters because if they happen to sit in freezing temperature at an airport loading dock in your luggage they will not work. Also have to mention I ordered the ceramic filters too and when they arrived they were dis-coloured and cracked/broken. And a pair of black filters I ordered failed the red dye test.
      Needless to say I can not trust Berkey filters and I wish someone could put together a class action lawsuit as they are peddling a product that is not safe.

      1. What kind of NONSENSE is this comment dear Graham.
        Millions of positive reviews about this filters and then your negative comment ?
        I know this filters after more then 6 years usage here in UK and all our co workers have them as well.
        I think your testing is wrong ! Also. You need to make sure you dont use organic food coloring to Red food die test. See full details here and also how to perform the test.
        And regarding the Ecoli test. Make sure you do this correct. Berkey never fails and i have never seen anyone saying anything like this. I think your testing are not done correctly..
        PS… ALL red food coloring in UK are Organic. Therefor u can not use them to test the filters.
        You NEED to use a artificial food col to test the filters.
        Like this one here is specially imported from USA and is 100% artificial.

        Please update me on this post as i think you are not doing the test correctly.
        All the best.

  75. Kudos for such exhaustive and excellent reviews of water filter for drinking. I’ve personally gone through many kinds of water filters in the market and I can attest that the best type of water filter for me is the water filter that is designed for drinking water like the Berkey gravity counter-top water purifier. To me the Berkey filters are the most practical and cost-effective gallon for gallon. I have been able to use my Berkey filters for more than 10,000 gallons of water and the cost per gallon is just a couple of pennies. Recently, I have travelled to developing countries like Malaysia where good clean water was not to be taken for granted – since I had to travel to remote areas in Malaysia to work. I was able to get a Berkey in Malaysia online store and I bought a Travel Berkey and I was so pleased with it because I could bring it everywhere I was traveling from hotel rooms to worksites, and the Berkey always delivered great tasting water and cleaned all the contaminants. I highly recommend it. I think it’s probably the best water filter I’ve ever owned.

    1. I’m surprised that no countertop or below counter filters driven by the household water flow are reviewed. They include some of the best NSF certified carbon block filters — great for efficacy, ease of use, and cost per gallon.

      1. Your right…I really love the filters from this small company in New York. I bought an under the counter three stage water filter and its been excellent ..they filter everything under the sun including Flouride and radiation. I wish they actually got more recognition but I think they are generally a word of mouth company… here is the site for those interested
        I went as far as calling the lab where they had tested their filter results to confirm that it wasn’t some gag…it all checked out and I got myself one. Couldn’t be happier. Good Luck!

  76. Yes we have. Magnesium level in our uk water is high and good. Magnesium and calcium in UK water and high and perfect for berkey as berkey doesn’t remove this good minerals. Only the bad and harmful minerals.
    Everyone should have a Berkey system at their home. I think most countries have some magnesium but at least the uk water have quite high level. So the uk water and probably all European water is perfect for the berkey system

  77. Great review of the Berkey purifiers.
    I bought a travel size Berkey filter from USA and packed it along with me during my travel to Malaysia because I wanted to have access to clean pure water whenever I was assigned to remote worksites like an oil rig and villages. It worked great for me as I was able to make purified water anytime I wanted especially when I was camping or staying at hotels. I’ve read some excellent reviews of the Berkey, so I bought a counter-top Big Berkey from a Berkey Water Asia Store
    Some reviews have greatly praised it as the best water filter purifiers in the world. I think after using it for 1 year, I must say I am very impressed with the efficiency and affordability of Berkey water filters. Thumbs up!!

  78. Hello there! I’ve been very interested how water filters do help the safety of my family. Although prices of these products varies, I think it’s a little expensive but I want to invest for up keeping the cleanliness of the water in my home.

  79. This has a top ten review worldwide. You should take a look at the Berkey water filter purifier. It’s a very powerful and affordable water purifier for drinking water. Requires no electricity and piping and is completely portable. It’s available in Malaysia at Berkey Water Asia Store. I highly recommend it as it has very good reviews and is considered the best gravity water filter in the world.

    1. You must try Livpure RO + UV + UF water purifier for the water issues. It has 8-stage filter that removes soluble and insoluble impurities. It kills and removes the virus and bacteria and maintains the level of TDS in water by removing excess salts and minerals from water. Every region has particular salts and mineral contents in water, which cannot be purified or balanced by a simple water filter. It needs an expert help. I am very satisfied with my water purifier and hence will suggest all to have installed a ro uv uf water purifier at home. See about this water purifier @

    2. I have a big berkey and love it. The water tastes great. It’s easy to use. However, someone recently posted on another forum concerns about the magnesium level in the filtered water. Any information about this?

  80. I like your reviews. I think it is unbiased. You should take a look at the Berkey water filter purifier. It’s a very powerful and affordable water purifier for drinking water. Requires no electricity and piping and is completely portable. It’s available in Malaysia at Berkey Water Asia Store. I highly recommend it as it has very good reviews and is considered the best gravity water filter in the world.

  81. Aside from distillation which makes water taste flat and completely removes all minerals, Reverse Osmosis removes maximum contaminants, leaves traces of minerals and does not waste water. The old systems did but most of the new systems recycle water or have valves that turn the system off the moment the tank is full. Highly recommend it. Check out and contact me directly at sales at freepurity dot com to custom built your own system if you don’t find what you’re looking for. If staying healthy and saving money is your goal. Reverse Osmosis is the way to go. FreePurity distributes top of the line, US built, wholesale systems.

    1. I have a Whirlpool hot and cold water dispenser and instead of using a refill station or taking the empty bottles for exchange, I was wondering if you knew of any filters I could install directly into the system.

      I found but it seems to be discontinued…

      also which seem to be available..

      just wondering if anyone had any insight!

  83. The only guarantee that a drinking water system meets a standard of quality is certification by NSF. Any certified product not only must meet established scientific standards for performance, but it must continue to meet those standards throughout its rated lifetime. This assures users that the certified system is of both quality design and manufacture. Cheap imported products with household names, under scrutiny, have actually been found to add heavy metals to the water they produce. So, a familiar name doesn’t mean anything, without NSF certification to back it up.

    1. Hi We bought from this company also and we live in Bangkok Thailand. They ship to here for only 20 USD. Took 4 days with DHL. We been using reverse osmosis for the last 5 years and we now have both Reverse Osmosis and Berkey. I like the taste better of Berkey and the water is supposed to be cleaner. So we are happy with our Berkey.

  84. In India these water purifier is not available. In India Aquafresh RO water purifier is most popular. It eliminates all kind of harmful chemicals and delivers a completely purified and safe drinking water but also maintains the level of the useful minerals in the water which is not possible by boiling the same.

  85. Thought this might be worth a share.

    I personally use products from Filtech, ( and I feel its cost-saving and effective at the same time. Used to have extremely sensitive skin and had rashes especially after showering, bought their water filter shower head and my condition improved a lot. Would recommend to all who’s looking for a cheaper alternative, the water filter singapore of my choice.

    You guys can go take a look at the products they offer.

  97. People please make an informed decision based on actual lab results and certifications, not “paid to endorse” and/or opinion pieces such as this article. Simply visit the NSF website yourself and see what the filter you’re interested in actually does…unless it’s something like Berkey, which isn’t certified by anyone. A filter that also can’t be sold in California because of lead content and came under fire for publishing falsified lab reports. ProPur isn’t certified by NSF to do anything other than improve the taste of your water. Meanwhile, many cheap, faucet attached filters such as Pur or Brita (both made in North America btw and not China, Taiwan, Malaysia, Korea, Mexico) are actually certified to remove more contaminates than most RO or under the sink units, including pharmaceuticals, VOCs, BPA and pesticides.

    1. Thank you for the suggestion to check the NSF site. Propur is, indeed listed, but the listing merely states “Conforms to material requirements only.” so I can’t say that their listing does anything to increase my confidence in the product.

      I’ve been looking for something to clear the taste, mostly. We’re currently using a Zero carafe, and while it makes good water, it’s expensive and can’t keep up with the demand (it was okay for just my cousin, but I drink more than she does and I cook). So far, I’m leaning toward a Berkey, based on what I read.

      1. Well, I would certainly see the listing as automatically increasing confidence and that is has the NSF 42 certification (which is all about aesthetics, ie : clear to the taste) considering the Berkey isn’t even NSF certified, although many opinions try to lead you to believe otherwise.

        1. The NSF website is a little hard to navigate but the water systems are there under each specific NSF standard. There are 2 different standards required. There are only 3 or 4 certified on the under counter systems.
          There are more listed under the whole house listing. But another way is to get the companies technical test reports. They will have the testing lab. Then call or email the lab. Some companies use fraudulent test reports.
          I backpack a lot and halve been thru all this to find my backpacking filters.
          Also know that there is a huge difference between “nominal” micron size and “absolute”. Nominal means that the micron size is average. Some bigger, some smaller. Absolute means that NO pore size can be bigger. I travel in crazy back country so use a .01 absolute micron filter that I emailed the testing lab to verify their test reports.

    2. Great comment. I read tons of pieces promoting the Berkey, and it may be great… but the one I had made the water taste like metal and did not inspire confidence. I got rid of it.

  98. Thanks. We use Berkey as well in our home and i agree. This is the best and most cost effective filters on the market today. We are family of 4 and we use Big Berkey. All the best. Lilly / / Portsmouth United Kingdom.

    1. I don’t have nay information on this company. It may be a good filter, but I can’t see that it’s NSF certified and there’s not much information about what the filters contain too.

      1. We have had the Radiant Life Filtration System for a little over a year now in our kitchen (separate faucet, the unit is under the sink). The water tastes great and pets, plants and people are all happy. I just tested the water and after one year still performing optimally. We love this system!

        1. Hi Melody,

          Can you tell me how you tested the water? I’ve been looking for a whole house water filter for the past several months but can’t confirm how they all perform aside from what they claim to remove.

          Thanks in advance,


  100. Pingback: Under Sink Water Filter Amway | Amway Products

  101. I live in CUBA where water is diabolical – cysts, bacteria, and other nasties etc Plus HIGH levels of calcium and magnesium. Bought a Berkey before leaving UK which is fantastic for our drinking water and I use to wash salad stuff and to cook with BUT trying to research whole house filter or Softener to remove ca/magnesium. Looked at Filter Butler and following this brilliant site also Pure Effect but am overwhelmed. Thinking I might also need an under counter filter in kitchen to help with preparing salad stuff as laborious to wash veggies spin them and then wash again in Berkey to rid them of cysts etc so under sink filter would be great – HOWEVER it will not deal with mag/ calcium problem which also has blocked my washing machine. I have hardly any wifi in CUBA – am in Miami for few days but not enough time now to order filter and get it shipped so I cantata it back to Cuba. Obviously there is no shipping directly to Cuba from USA or anywhere, so I will probably have to return here BUT would really appreciate some info/feedback/recommendations on what to do. Thank you.

    1. Joybell,

      It sounds like you’d got a challenging water situation there, and I’m not an expert in this type of filtration. Overall, a serious whole house filter would be ideal — but these filters require professional installation. I’d also suggest looking into capturing your own rainwater and storing it in cistern, if you happen be in a house with an available roof. You’d still have filter the rainwater, but it might be easier overall, given the issues with the municipal water. This book is a good introduction to rainwater harvesting.

      Given your limited time in Miami, an undersink filter might be your best bet. You might want to get it from a local vendor — just ensure that the filter is NSF certified for the contaminants you want to remove. Otherwise you could order overnight from a vendor like Pure Effect. Undersink filters can be installed by anyone how is somewhat handy with plumbing.

      A couple of other general tips that may be useful to you:

      – Using ozone is by far the best way to kill cysts and microbes in water (much more effective than chlorine or iodine). You can buy inexpensive (around $50) ozonation machines from places like Amazon — I use one myself in combination with drip filter.

      – Don’t be concerned about drinking hard water — your body can actually benefit from the dissolved minerals. Also, you can continue to scrub the deposits off the Berkeley candles until they are worn down.

      Hope this helps.

  102. Hi, I now live in Cuba where water quality is PROBABLY the WORST ever. Not only microbes, cysts, bacteria and other nasties but extremely high levels of calcium and magnesium. Before I left the UK for Cuba I researched water filters for ever and ended up buying an Imperial BERKEY in the UK, which we started using as soon as we arrived. I love it and use it for drinking and cooking.
    However the high levels of calcium/magnesium mean that my washing machine got blocked and even the inside of the Berkey gets a white coat. SO am thinking of getting whole house filter to install where water comes in from mains (live in Havana) before it reaches the cistern to eliminate the ca/mag BUT am also thinking an under the sink filter would be good for kitchen for washing salad stuff etc (at the moment I wash dirt of veggies and spin and then wash again in my Berkey but this is unbelievably time consuming. If I just get a whole house filter OR maybe a water softener to take out the magnesium etc there could still be cysts, bacteria etc in the water. I am in Miami for a few days where I came with the intention of buying my water filter and trying to get it back into Cuba but have spent days on the internet researching and only just came across this brilliant site. I have looked at Filter Butler which seem promising and some of the others mentioned like Pure effect, but right now feel overwhelmed and would appreciate some help. I think there is not enough time to order now before we return to Cuba and may have to come back to buy in the new year but would still appreciate whether to go for maybe just kitchen under sink filter (which one) or whether I need whole house filter/or softener to remove calcium/magnesium before water reaches kitchen. I already have Berkey shower filter so no worries there. Please note that there is no shipping to Cuba from USA or anywhere else for that matter and right now that doesn’t look like it will change anytime soon SO life span for filters and how often they need changing is also important factor. I have little wifi in Cuba and internet speed there is dire so researching is even harder for me so thank you for any input you can give me now.

    1. Thank you for your feedback. Actually I’m not worried about drinking hard water but its so full of calcium and magnesium that it’s destroying my washing machine and other stuff.
      However Ozone sounds interesting. DO you have a name or link to this so I can buy it quickly?

  103. Thanks for this. We own one of this Berkey Waterfilters and they even have a Lifetime Warranty here in UK.
    This was bought after loads of research and we highly recommend this filters. They can be bought here with Lifetime Warranty.

    I would also like to ask people to do a comparison as we did. There are so may filters out there and many brands that claim to be best. Berkey they are a true winners on the market and every water test in USA and Europe they come out as the winners.

    When it comes to our health we can not take any changes.
    They also last up to 11 years so that is a great thing too.


  104. Based on your reviews I purchased a gravity-feed water filter by ProPur. (ProOneG2.0).
    No where can I find a list of what this water filter is made of. I thought ingredients of all products MUST be listed on the Product Description.
    There are pages of What It Will Do For You…and flip mentions of wonder-materials, but no listing of the actual ingredients in the makeup of the ProOneG2.0, or other similar filters… EVEN the manufacturer’s (AquaMetix) site does not provide a list of what these
    filters are made of. Can you help me. Thank you Frances Smith

    Thank you so much. Frances Smith

    We are interested in your filter descriptions.
    We use Rainwater and would like more information about the dripfilters.
    What is the time involved to filter one liter of water.
    With all the pathogens etc you have listed which are removed with this
    method? Or please list those that are not removed!

  106. This is a nice post . Most of the diseases comes from water so it is better to drink purify water. This post helps me to buy a best water purifier for my home. Now a days there is a great problem of water pollution so every member of my home are very much conscious about water pollution . So thanks for writing writing such a wonderful post which helps me to buy a quality water purifier for my home.

  107. You should not drink distilled water or water that has been demineralized by reverse osmosis systems! This kind of water ir harmfull to your health, because ir washes out minerals from your body. Look up in the internet research by World Health Organization – risks of consuming demineralized water. Total mineralization of water should be from 250-500 mg/l . For example – Evian has 306 mg/l and Borjomi 5000 mg/l

    1. Yes! Completely agree. Reverse osmosis systems produce water that is devoid of minerals… it is essentially “dead water.” I’d opt for an Enagic anti-oxidant alkaline water ionizer when it comes to health and water purity (Obama’s cardiologist and hundreds of leading wellness specialists use only Enagic ionizers for their guaranteed purity, long-life, and un-paralleled health promoting benefits. You can buy an Enagic ionizer here:

  109. Hi there, I am chaitanya from India. Here, the TDS Levels in the water is high and the normal water filters are not capable of removing the hard metals like cadmium from the water. Most of the urban population use a Reverse Osmosis water purifier that costs around $300. A RO water purifier can remove all the dissolved and also add extra minerals like magnesium and calcium.

    1. I have some experience with the water quality in India as I work in this field, and as mentioned above, can say that reverse osmosis systems produce water that is devoid of minerals and essentially “dead water.” Enagic anti-oxidant alkaline water ionizers are becoming very popular in India due to its ability to remove most contaminants and to produce very health-promoting, high quality pure drinking water. Obama’s cardiologist and many wellness specialists use these Enagic ionizers for their guaranteed purity, long-life, and un-paralleled health promoting benefits. You can buy Enagic ionizers here:

  110. Mary, I don’t have any specific recommendations for whole house filters. However, I’d suggest starting with Puriteam — they have a lot info on whole house filters.

  111. You said that “Berkey is best-known drip filter manufacturer. They make good quality filters.
    You might also consider ProPur filters. Their latest filter, the ProOne G 2.0, will remove fluoride — including hydrofluorosilicic acid (few filters remove this contaminant)”.

    Does Big Berkey (with add on fluoride/arsenic filters) also remove hydrofluorosilicic acid?

  112. This could be a very dumb question….but can I filter collected rainwater with one of these filters to where it is drinkable? Or are these only made for tap water/well water?

    1. They say:

      Berkey purification systems do not remove the beneficial minerals from the water but they do extract harmful heavy metals such as lead and mercury as well as sedimentary minerals such as iron oxide. Therefore, the TDS (total dissolved solids) reading will not typically change much unless there are a lot of heavy metals or sedimentary minerals in the source water.

  113. While I was searching for water purifier I stumbled upon this awesome site.
    I like to introduce this portable water purifier made here in Singapore. This product has received positive feedback and satisfaction from all those customers. It has various capabilities and functions.

  114. very good post – just what i needed to see. clear, not overcomplicated etc. also, the comments are interesting as well

    i’m liking the sound of a gravity filter and i’ve found one from germany that i think is relatively new to the scene.

    this is the YVE 3000 BIO Filter – the glass one would be preferable but not in my range alas…
    this sounds like it ticks the boxes for an “entry level” filter that is for the counter-top in my teensy kitchen.

    i would be very grateful if you could let me know if you’ve heard of this model, and if you thought the description sounds right.

    i am currently working on my own website and am more than happy to give details of your website if you wish. i notice that you don’t have a pinterest link otherwise i would have pinned this !

    thanks, fifi

  115. I looked into the gravity fed, reverse osmosis…etc etc. But I the filter I ended up getting was a 3-Stage under the counter filter. It was the only one that I could find at the time that filters two things that almost never get filtered out….Flouride and Radiation. It caught my eye because of those two.

    On top of that it filters everything from Pharmaceuticals, VOC’s …etc etc.

    It’s a small company, but I can say that the customer service is absolutely amazing. I give it a huge thumbs up. Installation is really simple as I’m not much of a handy guy but was able to manage it just fine.

    Do yourself a favour and at least check out their website….they are based in NY.
    I got the Ultra-UC but they’ve come out with an additional one that has a UV light too.

    1. looking for a possible countertop water filter for well water being treated, whole house, with a WaterPro filter. We were required to add a some sort of potassium ingredient, now something else (don’t have info at hand) Still feel I need to have something else like a countertop filter. Tired of buying bottled water. I do know we have iron bacteria & do put bleach tablets in our well. Trying to find a solution. Thanks

      1. We bought the Enagic LeveLuk SD501 ( 9 years ago for our home and cannot say enough good things about it. It produces 7 different pH leveled waters that can help you go green and eliminate the need for chemicals around the house. For example, it produces a water that disinfects countertops and everything – completely natural. Nothing added. We don’t use laundry detergent anymore and we make our own soap from it, too.

  119. I’m looking for a filter that I can put in-line to allow the water to flow into our refrigerator for the ice maker and also into a small spigot on our sink. I would put it in the basement before both of these lines split. The RO system seems to be the only option in this that may work for that, but I’ve heard the water pressure may not be sufficient to run through a refrigerator. Do you have any recommendations on something that will work for me?

          1. Hi, I’m pleased to hear you will be doing independent testing of filters. I hope you’ll include filters from Friends of Water because they will demonstrate the quality to you. I will mention that there are certain requirements to get accurate readings when some media are used, so you need to use a lab that has the right equipment. If I can be of service please let me know.

  120. Please be aware on fake Berkey. DON’T BUY FAKE Berkeys ! Counterfeit products are being sold in UK and USA. – Make sure you only buy the Original products!

    We bought a Big Berkey online 2 months ago that was £20-30 cheaper from some website online and then few weeks later we started to get really concerned because it was always smell and taste of rubber in our water and a strong chemical smell in the upper chamber of the water..

    After we contacted to USA manufacturer they told us there are FAKE Big Berkey sold in Europe and USA now 🙁

    The reason for this rubber taste was the blocking plugs and parts inside and all other were not original Berkey products

    This is really shocking as it’s not safe to drink rubber contaminated water.

    We were able to return our Berkey and we bought the original Big Berkey from the official seller in UK and now we don’t smell or taste this anymore.

    For this expensive unit i recommend that everyone be aware of this before buying. We were trying to safe a little money here but were sold fake product.

    Our health is in stake here.
    It’s a shame for a good brand like Berkey to have this fake products sold.

    This fake Berkeys are sold underpriced and on small websites and ebay and so on.

    But after we got the real Big Berkey we have never been happier.
    And our water is 100% pure now and clean 🙂 Berkey really are the best filters on the market!

    Also thanks for a good post like always!
    I’m a big fan of Reactual site.
    Loads of good reviews and handy information here.

    All the best.

  121. Seriously considering buying a gravity fed water filter, either big berkey or propur with fluoride filters but unsure after reading mixed reviews which is the one to go for. The propur gravity filter with combi filters which remove fluoride and are washable/reusable would be the filter I’m leaning most towards purchasing but some reviews state it was not as effective as the big berkey. Really need a reliable, unbiased review.

  122. I am wondering the same thing as Caro: Pure Effect has countertop and undercounter filters that only filter at the sink and seem to be different than RO filters. Do you have any comments on these?

    1. Countertop filters are generally carbon-block types . Reverse Osmosis is a different process to straight filtration (see the article for details). In my opinion, Reverse Osmosis is not needed in most households. It requires maintenance and it does not reduce VOCs or pesticides (unless a Carbon Block filter is included).

      1. Hi, I would like to know if you have knowledge of the ProPur countertop option. To my understanding, the filter is similar to the gravity filter systems, but just in a different setup. Secondly, what is your thought on Crystal Quest filters?


    1. That is true. Just like reverse osmosis systems, distillation strips out the beneficial minerals from the water making it an acidic, “hypotonic” solution. To reiterate the danger of this, the repetitive drinking of mineral free water will cause a leeching of bodily minerals as part of the body’s natural mechanism to achieve homeostasis. Over time, depletion of minerals in the body will occur and can result in negative health consequences. We recommend adding a trace mineral supplement to the water post-distillation.

      1. What you don’t know or are not saying, is that while distilled water does indeed leech minerals from your body, it is only leeching the bad inorganic minerals which have been deposited over time in bones, joints, arteries etc. and cause arthritis, clogged arteries etc. THIS IS A GOOD THING.

        To distill and then add more of these inorganic minerals is counter-productive and dangerous.

        It is also incorrect to say demineralized water is “acidic”.

    2. That’s a load of BS. There are millions of people drinking distilled water and they are fine. If you’re really that worried, then you can add trace minerals to it. I guarantee you they are cheaper than the filters you are buying for berkeys, RO’s, etc.

  123. Have you heard of kitchen defender or the urban defender full house filter?the first is a three level filteration.
    When the owner claims that the filters use NSF certified technologies, is that enough or should the filter itself be certified?

    1. I’ve had an Alexapure Pro unit for three weeks now and i like it very much. After my Waterwise 8800 distiller “died” after nine years, I was going to buy a Berkey but upon researching went with the Alexapure Pro because it’s lab results are quite impressive AND it only uses one filter as opposed to the Berkey which requires a separate filter for fluoride removal. Also, if you buy it from Alex Jones’ website it’s $80 cheaper than the Berkey and they have free shipping! You won’t go wrong with the Alexapure Pro, imho.

  124. Hello love the reviews and your blog.was wondering how do you like the pure effects countertop water filter? Do you own one yourself? How long do the filters last for and have you tested the water before and after filtering?
    Thank you

    1. Water generators do produce good quality water (see this unit for example). They work if you have the right humidity and air temperature. You can expect to pay $1500 to $3000 for a residential unit. Also, they do consume some electricity each day.

  125. This one is a good article. I wanted to let people here know that you should only buy Berkey Filters from the main sellers and official sellers.. Seems like a lot of people is getting this knock offs and fake products from untrusted Ebay sellers and unofficial shops. There are many cheap knock offs on the market now and this is a expensive product and not a good thing to get some cheap knock off instead of the real deal..
    We live in London and we own a Berkey from the main shop here in London. Berkey Waterfilters UK (They are based in London) They are good and with a next day delivery service for free + and lifetime warranty.
    I can not give any info on the other filters mentioned here as we are happy with our Berkey Water filter.
    Only hassle is that it,s not possible to see the water level in the tank. Unless buying some extra part that was too expensive i think. But maybe later.


  126. I have a Brita pitcher and it is awful. There are visible particles left in the water. I use a paper coffee filter afterwards to remove these. Definitely worth spending the extra money on something better.

  127. I like the Berkey system! It removes the harmful contaminants from the water but leaves the minerals in it. The manual refilling might be somehow annoying, but I got used to it and on the brightest side, we didn’t have diseases so far. That’s even a good exercise. Lol Thanks for sharing this post! Keep it up!

    Which shower filter removes Thirhalomines in shower water?

    We are moving to Friday Harbor, San Juan Isalnd, Wa.
    There is no fluoride in water however there are Thirhalomines in water report – result of the chlorine used in their water sanitation process.

    Thank you!

  129. Can you compare the Ovopur unit you use with the Berkey and ProPur? Why did you choose Ovopur and why do you feel the need to supplement with the binchotan charcoal? My community’s source of water is from the Santa Rosa Creek and San Simeon Creek aquifers in California and I want to get the best product I can for this area. Thanks!

    1. The Ovopur is an expensive filter that has an aesthetic appeal. Unfortunately, I don’t have any data comparing these filters. I am getting ready to run some independent laboratory test on all these filters. I supplement with charcoal because I do not replace the Ovopur filters very often. Out of those three filter, I would recommend the Berkey filters, since it has the longest track record.

  130. Question: Will the Gravity-Fed Drip Filter, filter well water with water softener? (That is what my apartment complex has so I cannot change it). There is also a sulfur smell when hot water is run – not with cold. Thank you.

  131. Have you ever tested the Tarapur Water Ionizing System? What about Seychelle Water Pitchers?
    Are these hype? Can a water pitcher purify the water to 99.9% and others create alkaline water?
    Then lastly are the claimed benefits of Alkaline Water for real?

  132. Rob,
    I’ve used Zerowater pitcher filtering system for two or three years and my poor-tasting water here in Los Angeles goes from >400 to zero. It tastes wonderful, so much so that when I occasionally drink bottled water I definitely prefer Zerowater.
    Please take a look at Amazon costs for buying filter cartridges in bulk. I buy on subscription so they come on regular basis but I can adjust time frame if needed. They sell 8/$79.99 and if you have Prime the shipping is free.

    1. I also use the Zerowater pitcher filter and it’s an excellent water filter. I bought the stainless steel pitcher that included a PPM water monitor so I know exactly when to change the filter and what the current. If you are traveling or backpacking I recommend the Sawyer mini filter. In terms of cost and quality, these are two top choices. I often use both together in many less developed countries. They are both fairly lightweight, nimble and portable. If you are interested in a really interesting up and coming all in one travel filter, check out GRAYL Travel water bottle filter. It’s wildly impressive, but their replacement filters are a bit overpriced.

      All of the best,

  133. We want to purchase drinking water system for our industry and consumption is around 2000 ltrs. per day. please suggest suitable system,

  134. Dear As we are fast forwarding in the world where water is a precious resource and it is very important to keep it best available for the next generation. As i witnessed some things in the world which were beyond my recognition and hence i am sharing them here. As water is very important for our body, the type of water we drink can actual make a lot many effects and can increase or reduce health risk. As all i can say having an acidic water even after filtration can harm your body. the actual molecule of water is also important as their size and their effectivity can change the body and the blood behaviour. Alkaline and acidity are just two another terms. so choosing water purifier is more important when it come to your life and health.

  135. Hi,

    Have you had any experience or done any test on the Amway eSpring water filter? If yes, what is your feedback regarding the effectiveness of it? I currently am using one because my wife was told how good it is and how it removes contaminants while leaving behind nutrient rich minerals. I’ve been using RO filters all my life and love it and have never had any problems. I am hating the eSpring due to the taste of the water as well as the mineral buildup in my pots and pans as well as my portable water heater.





    1. Hello, I am a user of the Espring Water Purification System for more then 20 years. I am quite pleased with it and have not noticed any residue build up in pots or pans. The initial cost is around $1000 retail and replacement filter element is under $300. So with all the calculations the price per gallon after the first year is about $0.13. I feel this is well worth the investment.

  136. After this post i have bought 1 x Big Berkey from this company in UK
    My husband did read reviews for few days about them and also about the Pro Pur and Reverse osmosis waterfilters.
    Our conclusion is that Big Berkey and Pro Pur are the top of the line.
    We don’t think water should be ”messed with” and changed in any way like doing reverse osmomses.
    After we spoke with some salesman in Berkey that told us that Berkey water came out as water should be.
    without all harmful chemicals but still with all good minerals we decided to buy that one.
    We have now used it for 2 months and we are happy with it.
    Thanks for a good post though and great site! Alot of useful information.
    Kerstin & Andy (UK)

    1. @ Hi Kerstin
      We did the same here. But for your info. If you read more tests online and reviews, Berkey score much higher then this Pro Pur. Pro Put is a Berkey knock off and score not as high as they. But cheaper as well.
      But i agree with u. Berkey are the best and we love ours and they last longest of all filters too..

      1. Hi @GREG STONE . Please be aware to NOT buy on Amazon!¨ We placed an order last month and thought we are buying Big Berkey but they sent us some knock off type called British Berkeyfield.
        Also they are much more expensive on Amazon. They cost 30% more on Amazon.
        They are much cheaper to buy from the Berkey UK shop and they are Original too.

        We were able to return our fake Berkey and we have now Original Berkey and really happy with it. We even use the water for cooking and everything. 🙂
        They sell them for 239 GBP at
        But the one on Amazon cost 269 GBP + Shipping. :/

        Great post by the way and detailed and good info about todays waterfilters.

        But as i say it seems to be few types out there that is a Berkey knock offs.

  137. Hello, thank you for the great article.

    We are in the process of getting rid of the RO that we inherited from the previous home owner and find that gravity-fed drip filters very tempting. I heard that they won’t work on soft water, is that true? ( we live in an area with very hard water and have to use water softener so now the water is very soft)

    Thank you in advance!

    1. Thanks for the feedback. Gravity-fed drip filters do indeed work with soft water. They will work with any type of water, including questionable water from streams.

  138. Thanks BloomWorld,
    I am aware what kind of impurities activated carbon can block/remove. However, because of hypothyroid I am more concern about fluoride in the water. To get this chemical out I want to supplement Ovopur filter and Japanese binchotan charcoal also with bone char. One way would be to buy on amazon 100% organic hemp pouch filters for coffee, fill with bone char, put on a bottom of Ovopur and let it do the work overnight. Is this going to work? Does anyone have experience with bulk Bone Char from How small 20×60 mesh is? Please enlighten me on this subject.

    1. Val,

      The bone char needs a satchel with fine mesh, otherwise some of the char will slip though. I’m on vacation and I don’t have the exact details with me — sorry.


          1. Hi, I was wondering if you use bone char in a cotton muslin bag, how often should you change it? I was thinking about every six weeks or so ? Thanks

  139. Charcoal is carbon when it is treated with oxygen, it works as activated carbon. This process removes tiny pores of the charcoal which adsorbs the chemical impurities. It is basically used in the water purifiers to remove chemical impurities like chlorine.and other carbon based chemicals.When the water is passed through the activated carbon, it blocks the chemicals from moving further thus resulting in water free from carbon related chemicals.

  140. Your website was the most helpful in making decision what kind of water filtration system would be most beneficial for me. I read a lot then went ahead and bought Overpur and Japanese binchotan charcoal from your recommended source.
    Do you mind sharing test results with bulk Bone Char from I assume you bought 20×60 mesh (kind of small size). How do you use it and what kind of small satchel do you use (any source) to let Brimac sit overnight in water dispenser Overpur?

    Thanks for sharing your expertise and knowledge,

    California, Santa Barbara

  141. Any experience or thoughts on putting binchotan charcoal sticks in the bottom half of a berkey filter?

    I was hoping to improve taste a bit by mineralizing the water.

    Also would be interested if you had a source for legit binchotan.

  142. Hi! I am looking for a water purifying system for my home. I was offered the filter Fresca Pure 3000, or 5000, from Royal Prestige. These are not cheap, but they claim longevity and 99% effectiveness in cleaning the water. They also have an under the cabinet version (the 5,000 model) which is over $1,120! ouch! With the purchase they are offering the shower system as well, as a bonus.

    What do you think about these filters? Are there filters out there with the same capabilities at a lower price?


    1. Esther,

      I haven’t tried the brand you mentioned. I’d ask for their NSF Certifications on the filters.

      Generally, a whole filter will cost from $1000 to $3000. An under-sink filter should cost less than that.


  143. The The Superwater™ Whole House Filter with “Ceramet” sounds too good to be true.

    Is it?

    It’s advertised here in the UK, where we have very hard water. We’re trying to install a whole-house system, and I’m very glad to have come across your site!

    1. I haven’t tried that filter. However, watch out for filters that seem too good to be true. In the US, you can also ask for NSF certifications. I’m not sure what is equivalent is in the UK.

  144. Which one is more effective?
    Pure effect point of use filter or Promolife point of use filter.
    Promolife uses Bone char while Pure effect uses all-natural alumina-free activated carbon bonded with calcium.
    Both companies provide great filters.
    Anyone had any experience with both of these systems to comment on. Any feedback will greatly be appreciated.


  145. For Propur water filter, what kind of filters do you recommend for Fluoride, Chlorine, Chloramine reduction or have had good experience with.
    Is the flow rate decent with Propur?

  146. Another question. What water bottle would you recommend? I am trying to decide between the Berkey and the Clearly Filtered. Thanks again for you help!

  147. Was wondering if you have researched Clearly Filtered water products. I have read some really good reviews about the water pitcher and just wanted to know what you think. Thanks so much.

  148. The ProPur website states that they remove 50% – 95% for Fluoride from the water.
    I am not sure if this is an acceptable level or not.

    The whole house Pure effect filters cost about $1400. If you have 4 people in household, you have to change filters every six months for ~ $400. They do have good reviews but then it’s expensive to the point that lot of people can not afford to buy whole house filters from them.

    1. I have the Pure Effect Countertop fluoride filter, it’s very well made and less expensive.

      But I’ve seen some whole house systems sold for upwards of $3000, that claim you don’t need to change the media for 5 years, so you pretty much pay all the money for the filtration media upfront which gets stagnant and fouled over the years. Better to change it more often IMO, get fresher water that way.

      1. How long have you had this filter?
        Has this filter become saturated over time or has it stayed effective throughout the cartridge life?


        1. I’ve had their ULTRA countertop system for about 5 years now, and am very pleased with the quality and performance throughout this period.

          As far as the saturation, I change the cartridges at their recommended intervals, which allows me to replace the media BEFORE it gets saturated based on my apx. 1.5 gallon/day usage. I change them once every 12 months.

          They have conducted tests on some of the most difficult to remove contaminants, like chloramine (ammonia + chlorine) for example, and the system removed over 99% of it for at least 1000 gallons, that’s nearly 3 gallons/day for 365 days. So I know these are some powerful cartridges. They also recently did a test for Uranium, which also got removed over 99%. This is the one I have:

  149. Great post guys and this helped me alot! I been doing my own research here in UK and we have now bought a Big Berkey here in UK and i we LOVE it! Never tasted such a clean and nice water. There is alot of filter options out there but what i been reading the Berkey really are the best and they last so long too!

    1. What are your thoughts on Santevia mineralized alkaline water filtration? I have the gravity water system and curious to know if you would recommend it. Thanks!

  153. Is there a good countertop reverse osmosis filter out there that does not need to be hooked up to a faucet? I live in area that uses ground water and is rock hard with calcium, in addition to possible agricultural chemicals.

    Would love to not have to crawl under sink to replace filters or have cords and hoses running across the counter.

  154. Hello, I am looking at getting an under counter system for cottage lake water, after it has been treated by UV filter. I’m particularly nervous about drinking water originating at the lake but also am wondering if RO is the best option (main issue is it also removes the good parts of the water PRO is that it is safe). If it is the best option I will happily go that route, as safety is first. What would you suggest to be certain of safety – and is there a system that achieves this but also keeps in good minerals ? Also, if there is a sensor indicating when filter should be changed that would be ideal. I’ve spent hours and hours on line trying to find out the answer but haven’t lucked upon an article dealing specifically with originating lake water. Any feedback would be very much appreciated. Thank you.

    1. Hi, this is Sulia from Paragon Water System. Actually, Paragon have specialized on water treatment for 26 years, we don’t suggest our customer to drink RO filtration Water for long time, since RO machine only produce PURE WATER, then the helpful mineral substance in water will be filtered. However people need intake a balanced amount of beneficial mineral substance from the drinking water everyday.

      We prefer to suggest customer choose the American patented high-tech KDF process media, it can reduce chlorine, heavy metal, Hydrogen sulfide, bacteriostati, meanwhile it will not filtered the helpful mineral substance such as K, Zn… Anyways, it’s up to you.

  155. The Propur units look very nice and seem to filter out a good long list of contaminants. If I had a bigger kitchen and more counter space I would definitely get one. But since the gravity units need to be placed near an edge (sink, counter), I recently decided to get a Pure Effect water filter instead. I got the 3 stage filter style that attaches to the faucet. It filters everything the Propur does and replacement costs are slightly lower comparably over the long run. It also is endorsed by Debra Lynn Dadd, the queen of nontoxic living.

    If anyone’s interested here’s a link:

  156. Not to be a pain, but I don’t think you have deep experience with the Propur versus Berkey filters. I had the Berkey for 7 years and always loved it. I gave the propur a try because of good things I heard on the radio. Well, they turned out to be crap. Filtration was really slow and I had to replace them in like 8 months.

    So, I did some more research and found out that Propur is an ex-Berkey dealer trying to suck away business from Berkey. And, if you look closely at test results from both companies, Berkeys are tested for the life of filter, like 3000 gallons per filter. The propur is a one and done test. In other words, it’s not tested again at different intervals over it’s life of use. That’s shady as heck to me. I want a filter I can rely on at all times, not just when it’s brand new. Even when you look at the comparison chart on Propur’s site, there’s all this bad information about Berkey. It’s obvious they’re going right after their business and not be honest in the process. I stay away from Charlatons like that.

    I did see the black berkey issue you referred too, but from what I can gather that was a batch issue and the filters have been redesigned since, so I think that needs to be pointed out to be fair.

    1. I didn’t say Berkey filters were awful — I just that they made have quality control issues, based on recent customer reviews. It seems that your problem with Propur is that they are competing with Berkley. Propur units have a 100% stainless steel construction, and I’ve found that plastic spigots tend be the first thing to fail. In terms of water cartridges themselves, Propur now produces filters that remove fluoride, which is compelling to me. But I understand Propur doesn’t have a long track record, so I’m willing to be convinced that the filter cartidges have some drawbacks.

  157. I often wonder about those vending machines that fill your 5 gallon bottles with filtered water that costs 39 cents a gallon commonly found in grocery stores . there is also water shops dedicated to fill your bottles, sell bottles, water coolers, etc and they are a bit cheaper like 30 cents a gallon. Are those the best or better than buying your own water filtration system under sink or on countertop? As long as I am still young and able to haul heavy 5 gallon bottles ( I use 3 gallon bottles), am I buying the best drinking water money can buy ? what about water delivery service that costs considerably more, of course?

    1. I too used to self-fill 5 gallons of water (for as little as .25/gal) and had wondered if I could filter my own water at home with equal or better results for less.

      I also factored in gas, time, and convenience and felt that it was time. I found that fridge and faucet type filters didn’t yield acceptable results, so I started with a Brita pitcher filter. While it did bring my 201-226ppm avg. from the tap down to the 176-188 range, I felt I could do better. I next tried Whirlpool’s Everydrop filters hoping to speed up the filtration process, but it yielded worse results, only bring my ppm’s down an avg. of 5-15, less than half as well as the Brita.

      After reading this article, I was ready to invest in distillation or RO when I had stumbled on a Zerowater pitcher type filter. I was at Home Depot when I was asked if I needed any help- I had stopped to look at at in-home water filtration options, and when I shared that I was shopping for a really good water filtration system, he suggested trying the Zerowater pitcher.

      I was skeptical of the “000” claim of filtering ALL contaminates, especially for a $30 pitcher type unit, but I thought, let’s give this a try..

      Took it home and was thoroughly impressed! Through “de-ionization”, a process I’ve not heard of before (nor mentioned in this article), it effectively brought my 200+ ppm fown to an astonishing zero. I thought, what trickery is this? So I read up on it, went to their website, and watched several videos on YouTube and had concluded, this actually works!

      I have only owned this pitcher for 7 days, and have filled 3 1gal. containers and refilled at least 50+ 16.9oz water bottles and using my TDS meter, it’s still filtering my tap water down to zero.

      [using a water quality test kit from Prolabs, I verified the Zerowater filter is removing fluoride, aluminum, copper, nitrates, chlorine, and iron to 0-1ppm, however, it reduces the pH from 7.5 to just 3.8. I am currently experimenting with trace mineral drops to raise pH (as well as replace desired minerals) as well as infusing with fruit and/or baking soda to increase pH. I will report back within a day or two with my results]

      I have the 8 cup unit, so it took several pitchers and time to filter that much water, but I am super happy with the results and have recommended it to several of. Y friends. Replacement filters are $30 for 2 and says to replace when TDS reads 6ppm or more.

      So far, including water I’m giving my dog and water I’m using for cooking, I estimate I’ve filtered about 15 gallons of water that is equal or better than bottled. Buying this same amount in 5 gal containers would only cost me $3.75, plus gas vs. the $30 investment I’ve made so far, so I’do have to be able to produce roughly 10x more clean water on the same filter for this to be a better value (or with my avg. use, get 10 weeks or more from one filter). I’ll report back in 2.5 months (May 15th, 2015) with my results.

      1. I have bought the Zerowater system as well because I had read some good reviews on it. I was disappointed at how bad and plastiquey the water tasted over the first few runs even though I’d washed it and dried it carefully. My other problem is the acidity like you mentioned. It actually irritates my throat for hours after I drink the water. I’ve been putting baking soda in the water to help that. I was very disappointed at their customer service. They didn’t want to hear my concerns that maybe something was wrong with my filter and had a bad attitude. They told me to return it to the store if I wasn’t happy. I guess that’s my only option. When I later read other reviews I realized that there are actually many unhappy customers complaining of very many issues.

  158. Can you tell me about whole home water filtering systems? We have a lot of chlorine in our water and I’m not sure why I should use water pitchers, under the sink filters and shower filters when maybe one filter system will work instead of two or three. I can’t find any independent reviews for whole home water filtering systems on the web. Will you please shed some light on this topic.

    Thank-you in advance,

    1. Hello Shiro,

      I was interested in the Kagen SD501 Water Ionizer. Did you purchase one of these. There are so many out there, I am unsure of what one to buy. Prices vary greatly also. I know the Kagen is an opportunity to purchase and sell the water systems.

      Please give me some feedback.

    2. I have been using the Kangen for years, thinking that it was a water filter as well as ionizer, but was recently informed by a friend who markets Multi-pure (which I had used for decades) that Kangen water is not at all well filtered for contaminants. I am not sure what to do next as I was given the expensive Kangen water machine as a gift.

      1. Lucy, my family was just introduced to this option of water filtration. We signed on the dotted line but still have time to return since we have not received it yet… for some reason I’m on the fence with the VERY expensive purchase. Not so much the money, but the cleanliness of the water…
        Are you still using the machine? Does anyone else have anything to say about the Kangen® 8

        The Mighty 8-Plate Anti-Oxidizer?

    1. I have been utilizing the Kangen for quite a long time, believing that it was a water channel just as an ionizer, however was as of late educated by a companion who markets Multi-unadulterated (which I had utilized for quite a long time) that Kangen water isn’t at all around separated for contaminants. I don’t know what to do next as I was given the costly Kangen water machine as a blessing.
